The market rallied behind ACM Research, Inc.'s (NASDAQ:ACMR) stock, leading do a rise in the share price after its recent weak earnings report. While shareholders may be willing to overlook soft profit numbers, we believe that they should also be taking into account some other factors which may be cause for concern.

The Impact Of Unusual Items On Profit

Importantly, our data indicates that ACM Research's profit received a boost of US$17m in unusual items, over the last year. While we like to see profit increases, we tend to be a little more cautious when unusual items have made a big contribution. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. And, after all, that's exactly what the accounting terminology implies. If ACM Research doesn't see that contribution repeat, then all else being equal we'd expect its profit to drop over the current year.

Our Take On ACM Research's Profit Performance

We'd posit that ACM Research's statutory earnings aren't a clean read on ongoing productivity, due to the large unusual item. Therefore, it seems possible to us that ACM Research's true underlying earnings power is actually less than its statutory profit. But at least holders can take some solace from the 60% per annum growth in EPS for the last three. The goal of this article has been to assess how well we can rely on the statutory earnings to reflect the company's potential, but there is plenty more to consider.
